Legacy 2 is ok. I can’t put my finger on it; maybe it was in my head but it just didn’t feel the same. It feels better to me on Wii with the NES controller and scanline / CRT effects through a scaler.
I haven't messed with Wii hacking in a very long time so I had to learn all this from scratch. I don't like the Mega Man Legacy Collection 2 version of MM9, which I bought for switch. So, I eventually found this thread for playing it on Wii. I made a video showing how to apply these patches...
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
